近期情绪太不稳定了.可能是由于在找实习这个过程碰壁了吧.第一次面试就跪了,可能是我面的是一个新公司,制度不完好,我感觉整个面试过程全然不沾编程,我面试的还是软件开发-后来我同学面试的时候.说是有一道数学题了.最后都已经签了,orz...其它同学都陆续签了,有签了知乎.有签了猎豹的,有签了阿里的,我还在想着打比赛,作为一个快大四的人.我还想着打比赛.甚至我连队友都快没了-可是我还想坚持!到如今,我基本没课了,每天都仅仅能是刷刷题,写写python,搞搞shell,我都不知道我在干嘛-!有没有大神给…

                                     Largest Rectangle in a Histogram 这么经典的题硬是等今天碰到了原题现场懵逼两小时才会去补题...废话不多说: 题意:截取一个矩形使其面积最大,随你怎么截,反正面积要最大.输出最大面积,注意爆int. 思路:dp或单调队列.核心思路是从一个小矩形往两边扩散,分别找两边第一个小于这个矩形的位置,其中面积就是这个小矩形与区间长度的乘积,我们预处理出所有的小矩形的这两个端点值,然后扫一遍即可更新到最…

Problem Description A histogram is a polygon composed of a sequence of rectangles aligned at a common base line. The rectangles have equal widths but may have different heights. For example, the figure on the left shows the histogram that consists of…

目录 题目 思路 \(Code\) 题目 Largest Rectangle in a Histogram 思路 单调栈. 不知道怎么描述所以用样例讲一下. 7 2 1 4 5 1 3 3 最大矩形的高度一定是给你的高度中的一个. 我们枚举最大高度. 很明显以某一高度为高的矩形的左边界是该高度左边第一个比它矮的. 右边界类似. 我们可以用单调栈去维护每一个高度左右第一个比他矮的位置即可 \(Code\) #include<iostream> #include<cstring> #i…
